*Glue joints on old planes*
I recently purchased and old sport pattern plane and removed all of the old Monokote to bring it up to date with some new color and a brand new OS .61 FX with a Mac pipe. With planes that have been setting around for years, does the glue tend to weaken? Would it be a good idea to reglue the major areas especially around the firewall? Or do I just recover it and go on? Anyone have any thoughts on this???

I only have experience with ONE older plane and yes, it does tend to weaken.
This one flipped over on me on landing and landed on the rudder. It broke and when I stripped the covering off to repair, ALL the pieces (cross ribs and outer edge) just kinda fell apart on the table. The only thing holding the rudder in its shape was the covering !
Check any and all joints and give 'em a wiggle. You may find the glue doesn't exist anymore or is very weak to say the least.

Resurected an old Hustler delta with twin rudders, last flown in the late 60s. Flew for a couple of minutes when one rudder fell off, still flew fine. Couple of more minutes and the other rudder fell off. did the slickest flatspins you've ever seen
came down so slow, but spinning like a top. Did no damage other than to my pride. Epoxied them back on. Still flies fine.

Titebond and other aliphatic resins were used extensively in the past. If the airplane has been stored in a high humidity location (like in a barn) one might expect the glue joints to be soft.
Might want to remember that the stabilizer or rudder often falls off a new airplane. Usually they were not glued properly.
